My invention relates to a buffer for the picking arm in a weavingloom. The object of theinvention is to attain a soft movement of the picking arm by a provision of a simple device which is adapted to destroy the momentum of the picking am after it is o erated. The device consists of a pair of t 1e seat-ings and the pressing plates which are mounted on the slay and oppositely ar-' ranged across the passage for. the picking arm, a strap having a passage for the picking arm and interposed between mid seatings and pressing plates, said strap being adapted to be slid under friction, and a spring acting on the pressing plates for increasing the friction on the strap the sliding movement of the latter.

In the accompanying drawings in which. one embodiment of the invention is shown by way. of example:

Figure 1 is a front view of the devicelac' cording to'this'invention, Figure 2 is asectional elevation thereof,

Figure 3 is a front view of the check strap, and Figure 4 isa lan thereof.

will by the nut 10.

At each end of the strap 6, there are attached two check ton es lland' 12, one being diverged upwar y and the other diverged downwardly, which tongues are adapted to,engage with the picking arm A.

The 0' ration of the .as follows:When the, shuttle is thrown into the shuttle box on action on the other side, the picking arm A come into. engagement with the check tongues 11 and 12, whereby the strap 6 will be moved outwardly. V This movement is however restrained .by the increased friction between the strap 6 and the 'seatings 3and between the'former and the ressing plate 5, so thatthe momentum of t e picking arm Awill be destroyed by the strap 6.

tension of the spring invention is briefly one side by a picking Thus, it will be seen that, according to this invention, a soft movement ofthe picking arm may be attained by the provision of the bufier composed of the sliding ,strap 6.

What I claim is: a a 1. In combination with"the slay ofja loom and the picking arm, a buffer oomprisin seatings secured to the underside of said y, pressing plates, means connecting said p plates to saidseatings, a strap havmga ot for said picking arm and frictionally held between said matings plates, a spring act ng on said resmg ates for maintaining said strapzin frictions engagement with said 'seatin" said ressing; plates, and oppositel ing c och-tongues provided on sai each end of the slot therein.
